This paper proposes Runge-Kutta neural networks (RKNNs) for identification of unknown dynamical systems described by ordinary differential equations (i.e., ordinary differential equation or ODE systems) with high accuracy. These networks are constructed according to the Runge-Kutta approximation method. The main attraction of the RKNNs is that they(More)
This article proposes a new second-order learning algorithm for training the multilayer perceptron (MLP) networks. The proposed algorithm is a revised Newton's method. A forward–backward propagation scheme is first proposed for network computation of the Hessian matrix, H, of the output error function of the MLP. A block Hessian matrix, H b , is then(More)
BACKGROUND In the organ transplant process, the perioperative nurse plays an important role in assisting with organ procurement, during which they are frequently required to witness the death of donors. Their experiences and feelings regarding such are largely hidden and little discussed. PURPOSE The purpose of this study was to understand the experience,(More)
In recent years, Orthogonal Frequency Division Multiplexing (OFDM) technology has been widely used in many wireless communication systems, including LTE and WiMAX. Bandwidth is always precious over wireless channel, so it is important to have an effective bandwidth arrangement. On a multi-user system, each user needs to share entire bandwidth with others.(More)
The United Nations proclaimed that the year 1981 was the International Year of Disabled Persons. Countries worldwide vigorously promote a barrier-free environment to achieve the goal of equal opportunities and full participation. Therefore, providing disabled students with a barrier-free campus environment is an issue that demands substantial attention from(More)
Special protection system (SPS) can ensure power grids to operate in a satisfactory state following a contingency or major disturbances. By installing phasor measurement units (PMUs), the stability indices can be computed and applied to the decision system of a response-based SPS for recognizing the pattern of system instability. In this paper, the integral(More)
In our observations, some Japanese companies tend to ask their suppliers to become involved in their procurement of materials and/or joint product development projects, with undefined requests as proposals. We tried to comprehend this curious phenomenon by developing a unique analytical framework. We use the " Hiding hand effect " concept to explain how the(More)
Many family physicians still practice at an old age. Nevertheless, their practice patterns have scarcely been studied. To address this lack of research, the current study analyzed claims data for a total of 2,018,440 visits to 171 family physicians in 2011 sourced from Taiwan's National Health Insurance Research Database. Family physicians aged 65 years and(More)
